Cleaning composition



Patented Mar. 25, 1930 UNETE STATES PATENT OFFICE CLEANING COMPOSITION No Drawing.

Our invention relates to cl aning-compositions, having particular reference to liquid compositions miscible with gasoline for the removal of grease, dirt and foreign matter therefrom after the same has been employed as a cleaning agent for fabrics, clothing and the like.

Objects of the invention are: to provide a composition for cleaning and revivifying gasoline after use in the cleaning of fabrics,

clothing and the like; to provide a composition miscible with gasoline used as a cleaning agent, for washing the gasoline and precipitating grease, dirt and foreign mat tere therefrom; to provide a composition of this character which is in itself a cleaning agent and which may be used in conjunction with gasoline, or alone if desired, for all cleansing operations wherein gasoline may be used; and generally to provide a liquid composition for deodorizing, sweetening and strengthening gasoline used as a cleaning agent.

The ingredients, and proportions thereof,

herein disclosed, constitute the preferred embodiment in physical form of the principles of our invention, but it is to be understood that the specified proportionsmay be varied within reasonable limits without de- 3 parting from the scope of the invention, such variations depending upon conditions existing in materials cleaned.

The composition is prepared by dISSOlV? ing and suspending, substantially in the following proportions, 8 ounces of causticpotash, 5 ounces of powdered commercial alum, and 2 ounces of oil of eucalyptus, in one gallon of alcohol, the concentration of which may be varied to suit individual requirements.

In the preferred use of this composition it is mixed with gasoline which has been used as a cleaning agent, in variable proportions depending upon the exigencies of service. The caustic potash gives heat, sweetens the gasoline, and facilitates hydrolysis. The alum congeals the grease, dirt and foreign matter. The oil of eucalyptus is a deodorant, and the alcohol forms a solvent and carrier for the respective ingredients.

Application filed December 13, 1927.- Serial No. 239,814.

The solution of the above named ingredients is allowed to mix thoroughly with the dirty gasoline so that it may act upon and takeup the grease, dirt and foreign matter,

after which, being-heavier than the gasoline, it settles. and precipitates the impure matter, leaving the gasoline-free and in its initial state of purity.

It has been found that gasoline treated with this composition is not only cleansed but is revivified andits cleansing properties enhanced. This is probably due to the fact that some alcohol and caustic potash, with probably slight quantities of the other ingredients, remain in solution and in suspension in the gasoline.

In the use of the ingredients it has been found that the most effective variations in the respective proportions are from 5 to 8 ounces of the caustic potash, 3 to 5 ounces of the alum, and 1 to 2 ounces of the oil of eucalyptus- The composition is stable and in liquid form, retaining its effectiveness over a long 7 period of time. 1

We claim A cleaning composition consisting of substantially eight ounces of caustic potash dissolved in one gallon of alcohol and containing substantially two ounces of oil of eucalypso tus, said solution carrying in suspension substantially five ounces of powderedalum.

In testimony whereof we aflix our slgnatures. o
